GARBURETER ATTACHMENT.

Application sie@ .rum e4,

i, noiaon Slimme, e united States, residing et Los t, county ci' Los Angeles, and State Unifornie, have inveiitedet certain new and nsf-fui Cerbnreter Attachment, of Whic 'ioiowing is e. specification.

My invention relates to carburizing means ier internal combustion engines, and has perticuiar reference to an auxiliary. or supienta-ry sttachinent cci-acting with e carnreter and combustion engine, for utilizing;1 rhe Warm air, gases and vapors accuinuiatng in the crank cese during the operation oi the engine. y,

ne oi the objects oi" this invention is lo provide :i simple and eicient device that constitute an attachable complement to,

ci yform an 'integral part of, a. carbureter and by which the gas content of av crank case,

with the proper admixture of air, may be d. un inte andthrough the cerbureter, t reby assisting in keeping cool the engine,

preheating 1nd more extensively vaporizing enrbnreter mixture and enriching the @ther objects Wiii appear from the subeine? speciiicetion, in connection with the cconipsnying dren/ing, which represents one forni of embodiment of my invention,

end ii which motion, partly broken, and. a' sectionni 'vi' Y any invention in conjunction th, and

a. reine-ed pien View of my iii- Referring `tothe drawing, csibureter of known construction may corn-` pii'se an air pessage mining chzimberQ; and a frei suppiy 3, with the various other sggipurtenances essential to its operation.

chamber 4, formed with en annnus 5., whi isheid in position upon the Wal'is ci" the ini ing chamber 2, by a cap .6, or in any other substantiel manner. Communication tween the chamber 4 and the annuins established by a passageway 7. Sorewe" into vendl constituting e. part of the che i 1i, is a fitting 8, in the top oi" which is ce. e bali 9, forming a. veine for opening' fitting, @56; spectiveiy permittin the intake th porous mixturesen preventing,f back of the charge in the mixing chamberl 2. This ttingS is provided on one side with a con.'n stricted opening l1, through which etna pheric airmay be drawn, and on the otheside with a pipe 12, connecting 'the inet withv a breathing pipe i3 of s combustion e2- gine, or directly with the crank In operation, the vacuum produceemix'nig chamber 2,- by the pietonv or p.; 1 on the intake strokes, is extended thronethe passageway 7 in the ann-eins 5, to 'the chamber 4. This force iii-ts the neil frein lits seat on the duct 10, and draws iroin the crank case 14, through the pipe 'i2 and fit ting 8, a charge of air and vsp iis constituents that may have eccome voiatiinei by the heat generated'by the eng-me. Coi-iff rentiy with the inriish oi the crank cese atmospheric nir teken through stricted opening il, in qimntit for an enplosive mixture. rinis seppiemental. charge then enters thenmin mini chamber 2 and comminges with the fuel charge ofthe cerbnreteizn practice I hai/'e found that the ein?? case of e combustion engine, during openition, contains considerable fquantities oit Warm naporous or gaseous substonces.y herctofore permitted to 'go to waste, and eiicient utilization of the contents of crank case in the manner herein set out, resni la. decided economy in., and better gzisincttion, ofthe fuel.

` Obviously, the Withdrawai oi' part or nii le of the Vheated or veporized fluid from crankcase is foliowed by replacement with.'

' fresh air, and hence constant and. beneficial 'cooling is effected.

What I' Gleim, is: 1. An attachment for cerb'eretere prising in combinetion. with ze .ing chamber thereof, an nannies 'eo ifi-S upon *dio top of Suid mixing Chamber, n wip im' scouring said amiuius upon said Hubei; said annulus formed 'with a chamw extended outside of :uid free of the mix mg; Chamber and foi-med with a horizont'al may connecting said .mixing cham- .i Mie Chamber of said. annuhis, a ig connecting with said last named chamimvng an inlet, zuid u vulve in Said ein liber. An ntachment for cm'biueters comprising in combination with the main mixing .irhzmibel thereof, a hollow body im@ 'of said mixing Chamber, said hoiow body formed with an nnmxus arranged to sont upon the top of the mixing chamooi' und provided with a horizontal passagmvny connecting the main mixing chamber with said hollow body7 means to secure the :umuus upon the top of the mixing chamber, u fitting oomiev'ted with Said hoilow body having' ai imssagewny oommunicating with the atmosphere, a vulve in Said passageway, and a connection between said fitting and `the crank case of am engine.

n testimony whereof I have set my hand.
